Be sure that the power cable is securely connected to the unit and to the utility power supply.

The input circuit breaker has tripped.

Reduce the load to the UPS, disconnect nonessential equipment and reset the circuit breaker.

The unit shows very low or no input utility voltage

Check the utility power supply to the UPS by plugging in a table lamp. If the light is very dim, check the utility voltage.

The battery connector plug is not securely connected.

Be sure that all battery connections are secure.

There is an internal UPS fault.

Do not attempt to use the UPS. Unplug the UPS and have it serviced immediately

The UPS is operating on battery, while connected to utility power

The input circuit breaker has tripped.

Reduce the load to the UPS, disconnect nonessential equipment and reset the circuit breaker.

There is very high, very low, or distorted input line voltage.

Move the UPS to a different outlet on a different circuit. Test the input voltage with the utility voltage display. If acceptable to the connected equipment, reduce the UPS sensitivity.

UPS is beeping

The UPS is in normal operation.

None. The UPS is protecting the connected equipment.

UPS does not provide expected backup time

The UPS battery is weak due to a recent outage or is near the end of its service life.

Charge the battery. Batteries require recharging after extended outages and wear out faster when put into service often or when operated at elevated temperatures. If the battery is near the end of its service life, consider replacing the battery even if the replace battery indicator is not yet illuminated.
